You will find the right hand window to be a helpful tool. In addition to
identifying the waypoint you are currently approaching, it identifies
the waypoint at the end of the next leg. The really unique feature of
this screen is the graphical representation of your actual course line
approach angle relative to the next leg of your course. This approach
angle is continuously updated in real time and will help you setup for
. course changes.
Reset XTE and Skip Waypoint, described at the end ofNAV2, is also
available inNAV3.
NAV4 - Sensor Input Navigation
The NAV 4 screen applies the wind instruments, speed log, compass,
and depth sounder inputs from external sensors to your active route,
as appropriate. You can setup the sensors in the CFGl screen. The
Installation
&
Service Manual will guide you through the interfacing
capabilities of the CDU.
Use the following CFGl menus to set this screen up:
Compass - Sets the input port number, compass type (true or mag-

from which to derive the compass information. The NMEA 0 I 83
record should be specified by the user, because several NMEA
0183 records may contain compass information. This provides you
the capability of knowing the compass source exactly. The CDU
only accepts NMEA 0
I
83 formatted data for the compass input.
Synchro or stepper gyro compasses are not compatible.
Depth - Sets the input port number, units of measure for depths and
